Abstract

A rapid test method for evaluating the delamination in glass packaging is provided. The method includes exposing the glass packaging means to an atmosphere consisting of steam in order to form a corrosion zone; and subsequently carrying out at least one other step. The other step includes: visualizing the corrosion zone using a light microscope; visualizing the corrosion zone by a staining process with a subsequent inspection process; or removing glass components in ultrapure water and quantifying the removed glass components. The rapid test method provides a conclusion about whether a glass packaging exhibits a tendency to delaminate or not in a simple and reliable manner and in a relatively short time span.
